During the history of the Latter Day Saint movement, the relationship between Black people and Mormonism has included enslavement, exclusion and inclusion, and official and unofficial discrimination. Black people have been involved with the Latter Day Saint movement since its inception in the 1830s. Their experiences have varied widely, depending on the denomination within Mormonism and the time of their involvement. From the mid-1800s to 1978, Mormonism's largest denomination – the Church of Jesus Christ of Latter-day Saints – barred Black women and men from participating in the ordinances of its temples necessary for the highest level of salvation, prevented most men of Black African descent from being ordained into the church's lay, all-male priesthood, supported racial segregation in its communities and schools, taught that righteous Black people would be made white after death, and opposed interracial marriage. The temple and priesthood racial restrictions were lifted by church leaders in 1978. In 2013, the church disavowed its previous teachings on race for the first time.

The Church of Jesus Christ of Latter-day Saints, informally known as the LDS Church or Mormon Church, is a restorationist, nontrinitarian Christian denomination that is the largest denomination in the Latter Day Saint movement. The church is headquartered in the United States in Salt Lake City, Utah and has established congregations and built temples worldwide. According to the church, it has over 17 million members and over 99 thousand volunteer missionaries. As of 2012, the church was the fourth-largest Christian denomination in the U.S. As of 2023, the church reported over 6.8 million U.S. members.
